v Ports
v Performance features
v Management
– Four external 1000BASE-T ports for making 10/100/1000 Mbps connections to
a backbone, end stations, and servers
– Fourteen internal full-duplex gigabit ports, one connected to each of the
BladeCenter blade servers
– Two internal full-duplex 10/100 Mbps ports connected to the management
module
– Transmission method: Store-and-forward
– Random-access memory (RAM) buffer: 8 MB
– Packet filtering/forwarding rate:
- Full-wire speed for all connections. 148800 packets per second (pps) per
port (for 100 Mbps)
- 1488100 pps per port (for 1000 Mbps)
– Media access control (MAC) address learning: Automatic update. Supports 28
K MAC address
– Priority queues: Four priority queues per port
– Forwarding table age time: Maximum age: 17 to 2100 seconds. Default is 300
seconds.
– 802.1D Spanning Tree support. Can be disabled on the entire switch or on a
per-port basis
– 802.1Q Tagged virtual local area network (VLAN) support, including Generic
Attribute Registration Protocol (GARP) VLAN Registration Protocol (GVRP)
– Support for 256 VLANs in total, including 128 static VLANs
– Internet group management protocol (IGMP) snooping support per VLAN
– Link aggregation with 802.3ad support on four external ports for up to two
static trunk groups or two link aggregation control protocol (LACP) 802.3ad
link aggregation groups
– Spanning Tree Algorithm (STA) protocol for creation of alternative backup
paths and prevention of network loops
– Simple network management protocol (SNMP) version 1
– Fully configurable either in-band or out-of-band control through SNMP based
software
– Flash memory for software upgrades. This can be done through trivial file
transfer protocol (TFTP) or hypertext transfer protocol (HTTP) Web interface.
